    Nah sorry, my sump was already made. It was a cut 'n shut job. Stillen looks like he has a nicely designed one there though :)

    Didn't do plans for my sump either

    Just made it up as I went along. It the mark 2 version complete with flaps on the inside to stop oil slushing around. First 1 didn't work turn out to well

    The gearbox is a 6 speed manaul from a Ford Mustang - Tremec T56

    AndyMac Better than you

    Have you tried fitting the T56 in the tunnel? Is it the magnum?

    I was considering this box for a not entirely unrelated project, but Chispy shitcanned my idea as too much effort, so I stuck with the Zed box.

    The gearbox and block are in the car now

    A absolute butch to fit with the sump in place.

    i've been trying to dig into on the vh45 swap, but i really wish somebody could provide a proper engine mount design or a engine mount kit, and a diagram of how to wire it, i've tried to wire a gen 4 3sgte into my 1991 corona and gave up, and a shop wanted 2k to do it, all the vh45 swap builds ive seen have had half arsed engine mounts that simply would not get passed by an nz certifier...

    only a couple of people done the swap here, and they won't give me any info as they dont want others doing it so they can be unique....

    would be great to have but i just can't find enough solid info and how to to commit the money to it as much as i would like to i don't want to drop the money then get left not being able to do it...

    i have most tools, and a grunty mig welder and i know how to weld, but its just every engine mount ive seen so far has been rubbish...

    i'm digging through this thread now, so i'm not referring to this one from what i've read so far seems like thigns are being done right...

    would just be good to have a fully comprehensive write up, people seem to tell you some stuff then say figure out the rest yourself...

    i don't really like to throw money around like that lol....

    recession etc. :rofl:

    EDIT: just saw the engine mounts stillen posted, is it possible with this swap to use the stock z32 crossmember engine mount holes and make mounts to the vh to suit or do you have to modify all the engine crossmember as well? looking damn good by the way.

    not the same in the vg30de byu chance we did a bypass on my n/a and afterwards it was idling like arse, in saying that it blew up 30 seconds later because my mate hydrolocked it....

    Skid, I'll be posting lots of photos of the crucial components of this build ie. the engine mounts... most of what has been done up til now has just been pretty standard stuff. The whole swap will be looked over by a Consulting Engineer before I can get the Z rego'd so the engine mounts and such need to be quite decent.

    The thing with making engine mount kits and stuff is that everyone does it differently. I just went with the standard Z32 5 speed with an adapter plate from USA, and using the Z32 OEM crossmember so my engine mounts would only fit this kind of application... they would be useless for say, Stillen. Since he's opted to swap a VH45 auto bellhousing onto a Tremec box, which probably means a custom transmission mount and no adapter plate so his motor would probably sit further back than mine does.

    You can use the OEM crossmember and custom engine mounts to suit... you will need to modify the sump though.

    oh awesome bro, would u consider making up some more mounts the same to suit the oem corssmember if thats how you're doing it?

    are you using the stock gearbox position and drift shaft for the z32 though.

    if so then i'd be keen as if u wanna give me a price to make some up...

    saves me a shitload of head scratching...

    i'd also be happy to pay for a wiring list if u were willing to pull the tape off ya loom and let me know how its done...

    i wouldn't wanna pay more than say 300-400 for the wiring info and the mounts though

    This will also affect the oil capacity of the sump

    This will also affect the oil capacity of the sump; I believe it is potentially 3.5 litres compared to 5 litres with OEM engine mounts and a lowered custom cross-member.

    Alternative is custom cross-member with OEM engine mounts.

    I have written a 70 page document on my VH45 conversion PM me your email address if you want the PDF of this document.

    Instead of custom engine mounts you could go the modified cross-member with OEM engine mounts route; e.g. VH45 upper engine mounts and R31 lower engine mounts on custom engine mount plates.

    :rolleyes:

    I'm fully aware of the differences between the VG and VH cooling systems.

    The VH uses a wax expansion throttle control that lowers the idle when coolant temperature gets to operating levels. It doesn't have a AAC and FICD like the VG, only a IACV.

    All the info to put a VH into a Z32 is freely available on the net, you just have to go looking. There is plenty of info in my two build threads (~40 pages or so), click the link in my sig. Most of the piccies got lost when photodump crashed but if anyone needs anything in particular let me know.

    Check out Superhatches threads on NICO and V8Nissans for how to modify the crossmember to suit standard VH mounts.

    Npez's threads on NICO for the wiring document, I think I posted a link to it in my thread. The wiring isn't really that hard, as long as you know how to read schematic's and know how relays work it's really quite easy. Only took me 2 days to do mine and it worked first go.

    Look at John Dixon's threads on most Z32 forums on solid mounts and dry sumps, and solid lifters.

    Look at anything that Mettler did, fantastic read on VH41 into a R31. I use the same engine mount design, also used on various race and rally cars. Not quite solids and I've had mine Mod Plated no trouble.


    If you aren't prepared to have a go with the chance that it might all fall in a heap of steaming shiny bits you probably shouldn't do it.

    I was asking the question of if it works the same in the vg and if that would have caused idling problems in the vg when i had it....

    I have looked through your threads before about 3 months ago, and have done hour of research... i'm basically wanting to get mounts of somebody who has done it so i can just bolt it all together, i don't have time to fluff around with it, thats what money is for...

    you could perhaps consider replying to me in a more friendly mannor next time, rolling your eyes at somebody when they are asking for your knowledge when new to z's achieves nothing. and i actually asked you because i know you know your stuff.

    You really weren't very clear, I thought you were just saying that it was different on a VG which really added nothing to the thread... Some punctuation can really help ;)

    Yes, it is different on a VG. The coolant through the plenum has no effect on idle or operation and is only useful in very cold climates (maybe for you being in NZ).

    The mounts were the easy bit for me really. A bit fiddly getting the motor to sit flat, but not difficult. I had a heap of trouble with the sump, and the bonnet is good fun too.

    The wiring and mounts are about 10% of the whole thing, keep that in mind. You also need to modify/make new extractors to clear the chassis and steering arm. New inlet piping, gearbox adaptor etc, etc.

    Have a good read of Steven's conversion document, it's a pretty good place to start with a lot of info in the one place. If you still want to pursue it then read fully several build threads and see how you want to go about it. Front sump/rear sump, standard crossmember/modded crossmember, manual/auto, ps/no ps, aircon/no aircon etc. I haven't seen two VH conversions the same.

    It's a big job, I've been on and off mine for about 2 years now.

    My document can be updated with new info if required

    My document can be updated with new info if required ... e.g. RHD wiring diagrams as it is supposedly slightly different from the LHD.

    Yep I'm using standard transmission mount for the gearbox and so standard driveshaft as well. I'll start trying to whip up a model of the engine mounts I use as I'm learning Solidworks :D

    The downloads for the wiring diagrams on NICO are all not available anymore... I do have a copy on paper though...

    Oh cool man if you could even photocopy it and send me it or write it up i don't mind paying you something for the info on how to wire it up, me and wiring are not on speaking terms lol

    Hey,

    Sorry i should have been a bit clearer dude, it's been a long ass weekend lol.

    I'm not sure what path to take, would be nice to vh my z32 but i'm highly leaning towards selling once complete to build a 240z, then i'm stranded between vh and 2jz-gte for that, i think the 2jz would be better suited to the 240z.

    ahhh decisions decisions.
